Generally, you can go to the hospital at 12 weeks of pregnancy to build a file, usually in the obstetrics department of the hospital where you plan to give birth. The pregnancy file will record the basic information of the pregnant woman, as well as the results of previous examinations, and will also indicate the items of future pregnancy tests, the time of pregnancy tests and precautions. The main purpose of going to the hospital after pregnancy is to have a comprehensive understanding of the physical condition of the pregnant woman and the development of the fetus, and the doctor will decide whether to deliver by cesarean section or by normal delivery based on the previous pregnancy test records and the physical condition of the pregnant woman. You need to bring your ID card, birth certificate, maternity insurance card, pregnancy checkup report, etc. to the hospital. After the obstetrics department has built the file, you should follow the doctor’s instructions and go to the hospital for pregnancy checkups on time, pay attention to rest during pregnancy and not to exercise strenuously; pay attention to nutritious diet and not to eat spicy, cold and stimulating food.
